Turing Challenge

To celebrate Alan Turing being the face of the new £50 note, GCHQ have released a series of puzzles called The Turing Challenge. They call it their toughest ever puzzle but that's clearly a lie. I have the GCHQ puzzle book and most of the things in there make my brain hurt, but I raced through the first ten of these. Number 11 took a lot longer and I'm still a bit annoyed about it. And then number 12 had me raging about how pre-decimal coinage makes NO SENSE and I ended up having to reverse engineer some of the answers cos I'd never even heard of them! Still, it was a lot of fun and I loved doing it. And now I can feel smart and accomplished. Yay me!
